I have used IntelliJ for years. I have found nothing I prefer to it. It is absolutely, beyond a shadow of a doubt, heavier than depleted uranium.

VS on small projects feels pretty light. It's only on the larger projects and maybe Resharper in the mix that it becomes difficult

I haven't used IntelliJ per se but I've used CLion which is similar sofware from Jet Brains. To me, both feel super heavy.

It's not similar, it's the exact same code, just with features turned off. If I open a C project in IntelliJ it's literally the CLion plug-in.

They’ve piled everything on the UI thread like a freshman, now they are paying the price.
